About this study

Official title: Functional Impairment of Reading Ability in Dry Eye Patients and Effects of Sustained Reading on the Ocular Surface

To assess the reading function impairment in patients with dry eye and to assess the effects of reading on the ocular surface.

Read the detailed description

This study is being done to understand how reading is affected in people with dry eye in comparison with healthy controls and what effect reading has on the ocular surface in patients with dry eye.

Being tested
30 minutes sustained reading, Dry eye exam
Medical subject headings
Dry Eye Syndromes

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 30 minutes sustained readingOther

    The participants will be given a text to read silently in 30 minutes.

  • Dry eye examOther

    Tear break-up time, tear collection, osmolarity, Schirmer test, corneal and conjunctival staining.

Study groups in NCT01826812
Study groupRoleWhat they receive
Dry EyeThe patients with Sjogren Syndrome related or non-Sjogren Syndrome related dry eye. The participants will be asked some questions. Before and after reading a text silently in 30 minutes "30 minutes sustained reading", a detailed dry eye exam will be performed.
Receives: Other: 30 minutes sustained reading; Other: Dry eye exam
ControlsThe patients without dry eye. The participants will be asked some questions. Before and after reading a text silently in 30 minutes "30 minutes sustained reading", a detailed dry eye exam will be performed.
Receives: Other: 30 minutes sustained reading; Other: Dry eye exam

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sustained Silent Reading Speed

    Measured: 30 minutes

Secondary outcomes (4)
  1. Change in Total Ocular Staining Score (OSS)

    Ocular staining score (OSS) is sum of the corneal and conjuctival staining scores with a total possible maximum score of 12 for each eye. Corneal staining is graded with a maximum possible fluorescein score of 6 for each cornea (the punctate epithelial erosions grade between 0-3 plus any extra points for modifiers up to 3). Nasal and temporal conjunctiva are graded separately with a score range between 0 and 3 for each area after instillation of lissamine green. An abnormal OSS is defined as being a total score of 3 or more.

    Measured: Before and after 30 minutes reading

  2. Change in Tear Osmolarity

    Measured: Before and after 30 minutes reading

  3. Change in Visual Acuity

    Measured: 30 minutes

  4. Cytokines

    Identification of various inflammatory cytokines in tear film of dry eye patients comparing to controls.

    Measured: Tear samples were collected on the day of the exam. The samples were frozen to be assayed upon completion of the study.

Questions about this trial

What is this clinical trial studying?

An observational study of Dry Eye Syndromes, run by Johns Hopkins University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Mar 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sustained Silent Reading Speed (time frame: 30 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Feb 2018.
